amended April 30', 1928; 370 0. G. 757) This invention relates tocradles for transporting and supporting cylinders or containers of theoxygen tank type.

More particularly, the invention is directed to a cradle having a camlocking feature, a flat bottom to prevent the load from rolling andpairs of foldable handles. Latching means which engage the handles whenthey are in extended position and permit ready movement to foldedposition are also provided.

The improved cradle devices are used in sets of two and one of thedevices is provided with a metal arm support for the other device. Thearm support preferably includes a semi-circular portion which fits thetank when the arms are in folded position.

Cylindrical objects in tanks may conveniently be carried by two personswith lessened danger of accident.

An object of these improvements is to provide a locking strap type ofcradle which can be quickly secured to cylinders.

Another object is to provide a pair of supports having foldable handlesand which will prevent rolling of the cylinder when it is put down.

Another object is to provide a light cradle having a quick acting camlocking means and foldable handles.

These and other objects of invention will be manifest from aconsideration of the description, claims and drawings in which:

Fig. l is a top plan view of an oxygen tank to which a set of theimproved cradles are attached.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a side elevational view of a cradle device with an armsupporting strap.

Fig. 4 is a view of the cradle, in position on a tank, with handlesfolded.

Referring to the drawing, Fig. 1 shows an oxygen tank I with two'cradlesattached. Each cradle comprises a relatively wide metal strap ll shapedto engage the cylinder. Two supporting base portions I2 and I3 areintegral with the strap which is bent around as shown and welded at Mand I5. The ends of the strap do not come together, but are connectedthrough holes by eye bolt l6 and nuts H. The eyebolt I6 is connected toa pin I8 in bifurcated cam IS. The cam l9 has a knurled handle 20 tomove the cam into tank locking position and to release the strap forremoval from the tank.

Two pintles 2 I, 22 on opposite sides of the strap pivotally supporthandles 23 and 24. The handles are kept in position on the pintles bylock nut assemblies 25 and 26 which permit pivotal move- 55 ment of thehandles. it. pair g m s s-21 m 28 are secured to the strap II as bywelding; and when the handles are in extended position, act as a stopfor handles 23, 24, Arm support 30 functions as shown in Fig. 4 tosupport the handles when they are in folded position.

The parts of both cradles are identical with the exception of thehandles and supporting arm. Handles 32 and 33 may rest in support 30 toform a compact unit for storage. Like parts have been given likereference numerals throughout. It is to be noted that the locking cam isquickly operable, that the unit is light in weight and that danger ofinjury due to rolling tanks and disadvantageous lifting conditions areeliminated.

This invention may be made or used by or for the Government of theUnited States for governmental purposes without the payment to me of anyroyalties thereon or therefor.

What I claim is:

1. A cylinder cradle device, including a clamplng strap having a flatbottom portion, locking and release means for the clamping strap, a pairof pivoted handles mounted on the strap and latch stop means forlimiting the pivotal movement of the handles.

2. A cylinder cradle means including a clamping strap having fiat bottomportions integral therewith, cam locking and release means for thestrap, a pair of pintles on said strap and handles mounted for pivotalmovement on said pintles.

3. A cylinder cradle means including a clamping strap having fiat bottomportions integral therewith, an eyebolt and cam locking means for thestrap, a handle on said cam, a pair of pintles and a pair of stops onsaid straps, handles on said pintles which are pivotally moveable toengage the stops or to move to folded position.

4. In the combination set forth in claim 3, further characterized inthat the handles are joined together by an arm support member having asemi-circular portion and two straight arm supporting portions.

5. Cylinder transporting means comprising a pair of members removablyattached to the respective ends of the cylinder, a pair of handlescarried by each of said members and pivot means respectively connectingthe handle pairs to the members for selective movement to positionsprojecting inwardly of the ends of the cylinder and beyond the endsthereof.

6. Cylinder transporting means comprising a pair of members removablyattached to the respective ends. of the cylinder, 9. pair of handlesspective ends of the cylinder, 3, pair of handles carried by each ofsaid members, and amember carried by one pair of said handles forretaining the other pair of handles against pivotal move ment when thehandles are in folded positions.
